Information:
The Enhanced Network Block Device Linux Kernel Module makes a remote disk on a different machine act as though it were a local disk on your machine. It will acts like a block device (/dev/nda for example) on the local machine.
The remote machine usually shares just one file, not an entire partition. With this module, you can set up a RAID array over the Internet, allowing you to safely back up data across several machines in different locations.
